I am excited for this model. I love my Tremonti model more than any guitar I've ever owned, and one with a longer scale and a fixed bridge would be awesome for drop B stuff.
According to the site they ship with 14-68 gauges. Tuned to C#. I think something is a typo, either the scale length or those string gauges. Lol
Regardless, the guitar looks f-ing amazing!
No idea about finding it. But if you watch this old video with Brian McDonald you can get a glimpse of the whole guitar. It has a 6-inline Soloist headstock.

Yep that is an uncommon radius for an Ibanez. IIRC the Andy Timmons models are also 12" radius. Or at least his Premium models are. EDIT: the new Talmans are also 12".
